To celebrate the 25th anniversary of 1988's Die Hard, Fox Studios will unveil a larger-than-life permanent mural depicting Willis' iconic character John McClane outside its famous Stage 8 on the Fox lot. (You'll see a sneak peek of the mural in the upper left corner of this page.)

The mural will remain a secret until the unveiling on Jan. 31.

Willis will be on hand for the unveiling ceremony along with Jai Courtney, his newest co-star and onscreen adult son in the series' next chapter, A Good Day to Die Hard, out Feb.14. The new film's director, John Moore, will also be on hand.

The festivities will include a reception on the 21st floor of the Fox Plaza, a setting which played the part of the fictional Nakatomi Plaza in the original Die Hard. The new movie means that Willis will have portrayed McClane in five Die Hard movies including the original.

In a statement to USA TODAY, Willis says the franchise continues to draw fans for many more reasons than the love of the film's action sequences.

"While we're always pushing the envelope to create great action sequences, I think it is McClane's relatability and sense of humor that really draws in people," writes Willis. "I find it an interesting exercise to reach for the bar we set with the series, and I enjoy checking in with McClane at different stages in his life."
